' 3 Claims. (01. 248-142) My invention relates to heat transfer unitssuitable for heating automobiles, wherein the cooling claimed in mydivisional application, as described in the specification executed by methis 14th day ofDecember 1933. j

The object of" my inventionis to simplify the device, make it moreconvenient for installation,-

eflicient in operation, more durable and to avoid the constantannoyances caused by loosened,

parts, etc., to which units of this class are subjected. a

I accomplish these various objects by the use of hovel unitaryh ldinbrackets which are formed from" flat. stock and by providing meanswhereby thefan motor may be removed without disturbing theunit or thebrackets, and whereby the unit may be'removed without disturbing thebrackets or motor.

To'these and other useful ends this invention consists in matterhereinafter described and claimed and shown in the accompanying drawingsin "which:

Figure 1 is a side elevation of a car heating radiator equipped with myinvention.

Figure 2 is a. front elevation of the radiator and I brackets shown inFigure 1.

Figure 3 is a top plan view illustrating the supporting brackets, fanmotor and air directing means.

Figure 4 is 'afractional rearaview of the unit showing the air directingmeans in the position illustrated in Figure 1.

As thus illustrated, l0 designates the core of the radiator comprisingthe usual tubes'and fins,

II and I2 designate the usual headers having re-- inforcing plates l5which supply a suitable wall for openings into which to attach the pipes13 and 14 which are: suitably connected to the liquid cooling system ofthe enegine. The plates l5 and pipe connections are, as clearlyillustrated-in Figures l and 2, positioned on the front er the headersand in the center thereof. In the plates l5 and on opposite'sides of thepipe connections I provide threaded openings as at It, thus supplyingmeans for securing the supporting brackets to the headers, as willhereinafter appear. I Theusual practiceis to attach the heating uni tothe vertically positioned cowl board of the automobile providing roomtherebetween for the 5 fan motor which in the drawings is illustrated asan electric motor and designated by number I1.

I provide two unitary brackets made from flat stock and formed tothereby supply supporting means for the fan motor I! and the heatingunit, l0

which in its entirety is designated by reference character A. t v

The upper bracket differs somewhat from the lower bracket and is in itsentirety designated by reference character B. The lower bracket is desl5ignated by reference character C.

Referring now to bracket B, the rear end of. which has an upwardlyextending gusseted project'ion or foot 20. This foot is provided with anopening 2| for pipe I4. Openings are supplied-20 which register with thethreaded openings in the reinforcing plate l5 whereby the bracket issecured to the plate by means of bolts orscrews as s at H5.

The main body of the bracket B extends forwardly, having an abruptdownward bend as at 22- forming vertically'positioned gussetedprojections or feet 23 and 24, a strip of material having been removedto thereby provide these spaced 'apart feet, asclearlyindicated inFigures 2 and 3.-

Orifices 25 are provided to thus supply means for attaching these feetto the cowl board of the car.

The arm 26 is cut from the body of the bracket 3 and bent downward tothereby form a suitable upper support for the fan motor l1, theend ofwhich is made fast tothe motor bracket as at 21. In this design it willbe seen by scrutinizing the various views, that the material is suitablyribbed and flanged to thereby add to the strength and rigidity of thebracket; 40

The bracket C is similar to bracket B, except at its front end one footonly is preferably provided, thus to supply a three-point support at thecowl board for the unit A,'and further by dispensing with one foot, thernotor can be conveniently removed from the assembly. In bracket C,numeral 30 designates the rear foot. The opening for pipe I3 isdesignated by numeral 3|. This-rear foot is attached to the plate l5,asat l6, similar to bracket B.' The bracket C is bent a's'at 32,

the part 33 extending rearwardly and upwardly The arm 31 is cut from thebody of bracket C similar to arm 26 of bracket B and is shaped similarlyto thereby provide a bottom support for the motor I I which is connectedto the motor bracket as at 38.

For some installations it may be found desirable to use bracket B as thebottom support instead of bracket C or vice versa. Applicant thereforedoes not wish to be limited to either combination.

Thus it will be seen that the supporting brackets are light, strong,rigid and inexpensive, that the motor can easily be removed withoutdisturbing any other part of the assembly and that the heating unit Amay be removed without disturbing the motor or the brackets.

It will further be seen that by supporting the motor direct to thebrackets by means of the arms 26 and 31, the unit A fastenings to thebrackets are relieved of the weight of the motor and that the twobrackets are interconnected through the motor in a way which will add totheir strength and rigidity.

I have thus described my novel means for supporting the radiator unitand the fan motor therefor. The fan is adapted to force air through thecore of the radiator but, for various reasons, the operator may wish todirect the heated air as it leaves the core. I provide novel meanswhereby the air stream may be diverted in any desired direction in thefollowing manner:

A decorative housing 40 is provided and assembled over the front edge ofthe core and headers and having a central bar 4| formed preferably as anintegral part of the housing. This bar is provided with a centrallypositioned bolt 42, a spring 43 and nut 44. A fiat arm 45 is rotatablymounted at one end on the bolt 42 and positioned under the spring 43which is heavy enough to hold the arm in a fixed position unless movedmanually. The bar 4| has a streamline or air foil shape in direction ofair flow.

The air directing blade 46 is of a suitable shape and is provided with ahinge bar 41 which is positioned centrally near the outer edge of theblade, as indicated. The free end of arm 45 is adapted to partly embracethe bar 41 and is provided with a similarly shaped pad 48 and holdingbolt 49 whereby the pad may be tightened sufficiently to hold the bladein a fixed position but permit it to be moved manually.

It will be noted that the outer edge and ends of the blade slightlyoverlap the openings provided for air passage through the decorativehousing, whereby all of the air may be directed at will. It will be seenthat the blade can be turned a complete circle around the bolt 42 andthat it may be moved to any desired angle while in any position aroundthis circle, thus giving the operator complete control of the air as tothe direction it will travel after it leaves the radiator core.

One of the advantages of applicants air directing means is that thereare but two manual adjustments of the blade possible, one the angle ofthe blade and the other its position around a definite circle. Thus anyperson of normal intelligence will easily be able to secure any desireddirection of air flow into the car.

Various minor changes and position of parts 10 can obviously be madewithout departing from the spirit of my invention.

Having thus shown and described my invention, what I claim as new anddesire to secure by Letters Patent is: 15
